Xcellerate AIG vs Tailscale Aperture
A Tailscale-network identity gateway against a fully governed, EU-native control plane you run entirely on your own infrastructure.
Xcellerate AIG
Country of origin: Bulgaria
Bulgaria — inside the EU, so your data stays under European jurisdiction.
Tailscale Aperture
Country of origin: United States
United States — outside the EU, so customer data may fall under non-European jurisdiction.
On-prem without a US control plane
Aperture leans on Tailscale's US-hosted identity and coordination layer; Xcellerate AIG runs fully self-hosted in the EU, with no dependency on an outside network or vendor cloud.
Governance depth, not just access
Aperture is strong on identity-based access and key centralisation, but Xcellerate AIG adds budgets, tag-based chargeback, reversible data protection, adaptive routing and a tamper-evident audit log out of the box.
EU jurisdiction by design
Tailscale is a US company; Xcellerate AIG is built and run by RMM Labs Ltd in the EU, so your traffic and logs stay under European jurisdiction.
